INHIBITORY EFFECT OF ULIN WOOD LIQUID SMOKE AND GOGO RICE ENDOPHYTIC FUNGI AGAINST PATHOGEN Pyricularia oryzae

Biotropia: The Southeast Asian Journal of Tropical Biology, 2022
Diseases in rice plants (paddy) caused by microorganisms such as Pyricularia oryzae lead to a decrease in rice production. Therefore, it is essential to find out biological agents for protecting paddy and plants in general, against plant diseases ...

Pyricularia oryzae Causing Blast on Foxtail Millet in Iran

Plant Disease, 2018
Each year Pyricularia oryzae causes blast diseases of rice, wheat, and cereals of local importance (millets), which destroy enough food supply to sustain millions of people (Pennisi 2010). Blast disease is one of the major constraints for the production of foxtail millet (Setaria italica), especially in northern China and India (Nakayama et al.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Dual Role of Acid Rain and Pyricularia oryzae on Growth, Photosynthesis and Chloroplast Ultrastructure in Rice Seedlings

Agronomy, 2022
Rice is widely planted and serves as staple food in the world, but it is often exposed to acid rain and rice blast (Pyricularia oryzae). In this work, we analyzed the effects of co-exposure to simulated acid rain (SAR) and P. oryzae on the photosynthetic

lincRNA6679 promotes FnPR1B expression via phosphorylation‐activated FnWRKY14 to enhance strawberry resistance to Botrytis cinerea

Journal of Integrative Plant Biology, EarlyView.
In strawberry, Botrytis cinerea induces the expression of the long, intergenic non‐coding RNA lincRNA667，which upregulates the transcription factor gene FnWRKY14. FnWRKY14 then binds to the promoter of the pathogenesis‐related gene FnPR1B, enhancing strawberry resistance to B. cinerea.

A new method to measure EC50 reveals cultivar‐specific fungicide resistance and very high diversity within experimental field populations of Zymoseptoria tritici

Pest Management Science, Volume 82, Issue 4, Page 3613-3624, April 2026.
We isolated Zymoseptoria tritici strains from a diverse wheat field and quantified fungicide resistance using a novel plate assay. We found high diversity in fungicide sensitivity and host–fungicide–pathogen interactions. Abstract BACKGROUND Zymoseptoria tritici causes Septoria tritici blotch (STB), the most damaging wheat disease in Europe. In Europe,

Characterisation of Magnaporthe oryzae isolates from rice in peninsular Malaysia.

Czech Journal of Genetics and Plant Breeding, 2016
The genus Pyricularia (anamorph)/Magnaporthe (teleomorph) includes important destructive pathogens causing blast disease on various species from the family Poaceae. Thirty-five Magnaporthe isolates were collected from diseased rice plants (variety MR219)

Unraveling genetic diversity and loci conferring leaf blast resistance in East and Southern African rice germplasm

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Rice blast remains a major disease, causing severe yield losses in rice‐producing regions and posing a threat to global food security. Understanding genetic variation within germplasms is crucial for identifying locally adapted genotypes with beneficial alleles for improving resistance to this disease.

Bioactive Phytochemical Compounds in Medicago sativa L. (Alfalfa): A Systematic Review of Biological Properties and Therapeutic Relevance in Nutraceutical and Functional Food Implications

Food Frontiers, Volume 7, Issue 2, March 2026.
ABSTRACT Medicago sativa L. (alfalfa) harbors a remarkably diverse reservoir of bioactive secondary metabolites. Flavonoids, isoflavones, and triterpenoid saponins dominate its bioactivity landscape, driving potent antioxidant, anti‐inflammatory, antimicrobial, estrogenic, hypolipidemic, and cytotoxic actions through redox modulation, membrane ...
